Context

• Tax-withholding dispositions (code F) are routine administrative actions when restricted stock vests; they are not the same as an insider choosing to sell shares on the open market and typically don’t signal a change in sentiment.
• The filing also documents outstanding Performance RSUs that will settle at the end of their respective performance periods upon Compensation Committee certification; those future settlements may result in additional shares or future tax withholding events.
